The equation (2x^2-1)(3x+2)=(2x^2)(3x)+(2x^2)(2) +(-1)(3x)+(-1)(2) is an example of which method/property?

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
